Abstract

Die Erfindung betrifft ein Flurförderzeug, insbesondere Gabelhubwagen, mit einem Antriebsteil (2) und einem Lastteil (3), wobei im Bereich des Antriebsteils (2) zumindest ein lenkbares Antriebsrad (4) und mindestens eine Schwenkrolle (5) angeordnet sind, die um eine vertikale Achse drehbar und vertikal bewegbar am Antriebsteil (2) gelagert ist, und wobei im Bereich des Lastteils (3) mindestens zwei Lastrollen (10) angeordnet sind. Die Aufgabe, mit geringem Bauaufwand eine hohe Stabilität und Standfestigkeit des Flurförderzeugs zu ermöglichen, wird erfindungsgemäß dadurch gelöst, dass die Schwenkrolle (5) mit einer Arretierungseinrichtung (30) in Wirkverbindung steht, mittels der die Schwenkrolle (5) in Abhängigkeit von zumindest einem Betriebsparameter des Flurförderzeugs (1) in vertikaler Richtung festsetzbar ist. Gemäß einer Ausführungsform der Erfindung steht die Schwenkrolle (5) mit einem federbeaufschlagten Hydraulikzylinder (20) in Wirkverbindung steht, wobei der Hydraulikzylinder (20) einen Federraum (25) aufweist, in dem eine Feder (24) angeordnet ist und die Arretierungseinrichtung (30) zumindest ein Ventil (31) aufweist, das das Ausströmen von Druckmittel aus dem Federraum (25) des Hydraulikzylinders (20) steuert.

The invention relates to an industrial truck, in particular a pallet truck, having a drive part (2) and a load part (3), at least one steerable drive wheel (4) and at least one swivel roller (5) being arranged in the area of the drive part (2) vertical axis is rotatably and vertically movable on the drive part (2), and wherein at least two load rollers (10) are arranged in the region of the load part (3). The object of enabling the industrial truck to have a high level of stability and stability with little construction expenditure is achieved according to the invention in that the swivel castor (5) is operatively connected to a locking device (30) by means of which the swivel castor (5) is dependent on at least one operating parameter of the industrial truck (1) can be fixed in the vertical direction. According to one embodiment of the invention, the swivel roller (5) is operatively connected to a spring-loaded hydraulic cylinder (20), the hydraulic cylinder (20) having a spring chamber (25) in which a spring (24) is arranged and the locking device (30) has at least one valve (31) which controls the outflow of pressure medium from the spring chamber (25) of the hydraulic cylinder (20).
